DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT "

OBJECT OF THE INVENTION The present invention relates to a metal structure of the modular configuration type, made by combining a minimum set of mounting and connecting elements to determine a wide variety of construction models and elements. The fundamental application of this construction consists of the assembly of trade fairs of type stands and accessories of stands.

Other applications include some of the fixed type elements such as walls, partitions, etc. The structure of the present invention is made up of a set of profiles in multiple combinations with fasteners which determine the fastenings between all stand shelves and partition walls , together with other construction elements such as ceilings, closed displays, open display elements, etc., with a wide variety of combinations and connecting devices, some of which are rigid and others are hinged and have a variable angular assembly.

BACKGROUND OF THE INVENTION There are different ways of constructing metal modular structures such as those described in German Patent No. DE-U 9304055 in which a hook is used which does not have its ends hinged and the other two ends of the hook are not prepared for an inclined contact, and the support profile has only one channel defined.

In European Patent No. EP-A-0248122 the support profiles show tabs defining a single channel.

In U.S. Patent No. 4,583,359 there is disclosed a way of tightening the two transverse portions using a hook which is introduced longitudinally into a longitudinal inner space and the other part into an outer fitting of another tube. The wide diffusion of aluminum alloy profile elements for use in a wide variety of new activities as well as other activities traditionally reserved for conventional iron constructions has generated an extremely diverse multiplicity of profiles and accessories used to connect such profile elements.

In fields such as fixed or sliding partitions, revolving, sliding or hinged doors, as well as in large open spaces, the progress achieved in the construction of these new profiles has been well demonstrated. Notwithstanding the foregoing, there are fixed-structure facilities which are constructed so that they can be dismantled for further installations, just as there are others that are not recovered after brief periods of use, such as stands at trade fairs and exhibitions.

Both types require attachment devices and mounting and dismounting means which must necessarily be of the easy-to-operate type in order to take these competitive products which require the existence of profiles and connectors specially prepared for such purposes, that is, profiles and parts not usually found in the market. The existence of rigid junction pieces can be similarly observed in the construction of conventional metal installations which, due to lack of luminosity, require the compensation for structural adjustments normally required in metal installations. The advanced solution consists of the combination of various types of metal profiles with a number of mounting parts resulting in complex and varied connections and installations.

The variable angle and pivot attachment devices consist of a set of cross member connecting elements constituting a double piece, in the configuration of a hook hinged at one end by a semi-cylindrical projection housing a cutout of similar shape defined in the other half of the hook-shaped piece.

The ends of the parts are configured so that the hook engages as an inclined seal, closing the part, engaged with the semi-cylindrical projection on the other part. The region of the first end has two projections and two slits or cutouts which nest within the corresponding channels defined by the inner elements of the projections on the wing of a support profile. The hook is inserted, after being assembled, into a housing suitably configured for embedding the hook, made of a cross-sectional element to which the hook is then connected. 5

One of the parts has, centrally located and close to the contact area of the hook end, a threading hole for the passage of an Allen pin which, at the same time, passes through one of the surfaces of the profile, the hole coinciding with a rectangular internal trim in one of the parts, which is identical to the other in the opposite part on which the front surface secures the Allen bolt. The pin pushes and, because of the progressive pressure, opens the hook through the hinge until it is rigidly housed within the housing profile, thereby giving rigidity to the joint between the two transverse profiles. The hook may be cut obliquely from two of its opposite diagonal vertices of one of its larger surfaces, this cut allowing the hook to engage the profile also cut obliquely, thereby configuring it with a tie, a post of a grid, a slanted panel, etc.

The rigid connection devices are made of an octagonal cross-sectional profile whose vertices are externally and radially outwardly disposed between two consecutive tabs forming a channel.

Each channel has a double arrow profile and between each double arrow profile a channel is formed into which irregularly shaped washers 6 are introduced with circular sector cuts and other fully external washers for tightening, or alternatively the washers can be replaced by a circular piece of external octagonal shape, which operates as a guide and as a support for the transverse connecting profile.

A profile having a square inner section and with projections on two, three or four sides constructed with projections and inclined downwards may also be constructed with a function identical to those described with reference to the above octagonal inner profile and with the same aim. Surfaces are provided that do not have projections allowing the connection between profiles with a curved convex end.

The fundamental profiles to be combined with others and through the use of mounting pieces have an angular connection, with angles of 45 °, 90 ° or 135 °, in the same plane, using central projections of the profile structure constituting the inner profile These structures can also be connected perpendicular to the profile surface, one or two profiles that fit into the transverse projections of the structure, which are constructed with different external models, polygonal simple or polygonal lateral curves.

Internally, these profiles may have square or polygonal interiors. DESCRIPTION OF THE DRAWINGS

PREFERRED EMBODIMENT OF CARRYING OUT THE INVENTION

With respect to FIGs, the present invention consists of a combination of metal profiles with other mounting pieces, resulting in a wide variety of connecting devices, through the hinge and at varying angles, as well as with rigid connections.

The devices used for connecting through pivots and having variable angles for connecting transverse profiles have a hook consisting of a first part (1) and a second part (1 '), hinged at one of its ends by a semi-cylindrical projection (4) with two projections (5) of the first part (1) which engages a cut-out (3) defined by the second part (1 ') at the opposite end, the parts are of different lengths and are arranged for an oblique contact , and two apertures defined by the projections (6) that fit into channels of similar configuration (30, 30 ') on the handle of the support profile (7) to which they are tightened. The rest of the hook is then inserted into a housing structure (8) of a transverse profile (9) to which the hook is then tightened by the action of a screw (10) through a hole (11) and a trim (12) in the thereby exerting pressure against an opposing gasket 12 'on the opposing member 1' thereby giving rigidity to the gasket between the support profiles 7 and 9. The hook must be cut obliquely so as to fit into an equally oblique profile 9 ', for example, having the shape of a tie, a grid, an oblique panel, etc., without losing the ability to adapt the use of variable angles, to the general requirements of the structure.

The rigid connection devices have an octagonal profile (13) and are designed with radial lugs (14) defining channels (15) into which washers (16) are to be inserted together with clamping washers (10)

(17) or locking washers (16) and an octagonal part (18) which functions as a guide and a support of a conventional profile.

Referring to FIG. 5, a square profile 13 'has tabs 14' protruding from two, three or four surfaces, with a function identical to that of the tabs 14.

Surfaces (19) not configured with said tabs (14 ') form a convex curved end.

The profiles are assembled using angular rigid connections with angles of 45 ° (20), 90 ° (21) and 135 ° (22), within a single plane, using shafts (23) to fix the angle capable of being screwed into the the structure (24).

These constitute the inside of the profile, acting as beam, pillar, crosspiece, base, support, &quot; etc ..

The structures 24 'are then capable of being assembled as some profiles as required using the transverse remaining axis 23' of the structure, and must be configured either only polygonally or polygonally with the curved side, the profiles having an octagonal interior or square, as a function of the extension of the part.

It is not considered necessary to further extend this description to enable a person skilled in the art to understand the invention and the advantages thereof and to enable its reproduction. LISBON, OCTOBER 10, 2001
